NEET BIOLOGY

Detailed explanation-1: -Archaea that live at high salt concentrations are a phylogenetically diverse group of microorganisms. They include the heterotrophic haloarchaea (class Halobacteria) and some methanogenic Archaea, and they inhabit both oxic and anoxic environments.

Detailed explanation-2: -Most commonly observed halophiles are Archaea and Bacteria such as Halobacterium, Halomonas and Salinibacter [1].

Detailed explanation-3: -Halophilic Archaea (or Haloarchaea) thrive in environments with salt concentrations approaching saturation, such as natural brines, alkaline salt lakes, the Dead Sea and marine solar salterns.

Detailed explanation-4: -Bacteria that grow in the absence of salt and in the presence of high salt concentrations are known as halotolerant.
